The top-level LinearLayout uses a horizontal divider to visually19
distinguish the top description box, list, and bottom button bar.20
21
android:showDividers="middle" draws dividers between each child view and22
android:divider="?android:dividerHorizontal" indicates that the standard23
horizontal system divider (set in the activity's theme) should be used to24
draw the divider.25

Remember to use padding on your ListViews to adhere to the standard40
metrics described in the Android Design guidelines. When doing so,41
you should set the android:scrollbarStyle such that the scrollbar42
doesn'isn't inset.43

<ListView android:id="@android:id/list"45
android:layout_width="match_parent"46
android:layout_height="0dp"47
android:layout_weight="1"48
android:paddingLeft="@dimen/page_margin"49
android:paddingRight="@dimen/page_margin"50

When using the Holo theme (setting your activity or app theme to54
Theme.Holo or one of its descendants), a LinearLayout with the55
?android:buttonBarStyle will draw dividers (with padding) between56
buttons.57
-->58
<LinearLayout style="?android:buttonBarStyle"59
android:layout_width="match_parent"60
android:layout_height="wrap_content"61
android:orientation="horizontal">62

<!--64
Make sure to apply the ?android:buttonBarStyle to each button65
in the button bar.66
67
In the Holo theme, this style is very similar to68
?android:borderlessButtonStyle, but designed for use specifically69
in horizontal button bars.70
